Maxbotix manufacture many sensors which can withstand harsh outdoor conditions. When dust, moisture, or harsh handling of the ultrasonic sensor is unavoidable, then this MAXBOTIX MB7139 XL-TrashSonar-WR Ultrasonic Sensor Trash Bin Measurement is ideal for your application.

This is weather resistant Maxbotix Ultrasonic Sensor which can be used in indoor as well as outdoor conditions. The XL-TrashSonar-WR sensor series provide users with robust rang information in the air. These sensors also feature high-power acoustic output along with real-time auto calibration for changing conditions (supply voltage sag, acoustic noise, or electrical noise), operation with the supply voltage from 3.0V to 5.5V, object detection from 0-cm to 350-cm, and sonar range information from 20-cm out to 350-cm with 1-cm resolution. Objects from 0-cm to 20-cm typically range as 20-cm. It has read rate of 10Hz.

Features of the weather resistant MB7139, XL-TrashSonar-WR, include centimeter resolution, short to mid-distance detection and various output options: pulse-width, analog voltage, and RS232 serial.

The MB7139 from the XL-TrashSonar-WR line of outdoor sensors is a rugged ultrasonic sensor component module. This sensor comes in a compact and robust PVC housing which meets the IP67 water intrusion standard and matches standard electrical 3/4‑inch PVC pipe fittings (this product has multiple housing options available).

The XL-TrashSonar-WR sensors are factory calibrated to match narrow sensor beam patterns and provide reliable long-range detection zones.

In addition, the MB7139 offers virtually noise free distance readings through the use of high-output acoustic power combined with continuously variable gain, real‑time background automatic calibration, real‑time waveform signature analysis, and noise rejection algorithms. This holds true even in the presence of many of the various acoustic or electrical noise sources.

Note: This module doesn’t come with F-option(equips chemically inert material’s covering to the sensor) or P-option(applies Parylene coating on the Aluminum transducer) protection. To buy MB7139 XL-TrashSonar-WR ultrasonic sensor with F-option or P-option please contact us at support channel.
